- Designing and manufacturing a fuel system is a lot more complicated than most think. Not only dos the R&D cost a lot of money, but so does the certifications/standards required. Since it is an emissions component or system, you have to attain and/or abide by many different certifications/standards wherever you sell an engine with this system. These certifications/standards will change from one region or country to the next, and a lot of it is more political than environmental. Then you also have more liability as well.
This is a major reason why almost all(if not all) diesel engine manufacturers from BMW to Cummins don't make their own fuel systems. It is not just a diesel thing either, most HPFP fuel systems on the direct injected gas engines are made by Bosch or other suppliers as well. - WOW.....
almost 15 pages of this banter back and forth !:S - Does Cummins use the same pump as Powerstroke cuz I just read that the Cummins has a 29000 psi fuel delivery system where as Ford claims they went to 36000 psi for 2020? I think both use the Bosch 4.2. How does that work?
Edit: Upon doing further google searches I found evidence of a CP4.2 pump failure in a 2020 Ford. Even if the pump has been changed for 2020 it sounds as though it’s still a POS. It seems almost unbelievable that Ford would stick with Bosch even if the number of failures are rare the damage these failing pumps do to the Powerstrokes reputation has got to be costly to Ford.

Rumor has it the RAM/Cummins is going to have a different IP next year. I guess the pain of failures at around 10K is getting to them. Service writer said they were seeing a log of failures and no parts available to fix them for weeks and weeks.
Are they going to a different manufacturer or is Bosch coming out with something new?- Rumor has it the RAM/Cummins is going to have a different IP next year. I guess the pain of failures at around 10K is getting to them. Service writer said they were seeing a log of failures and no parts available to fix them for weeks and weeks.

Sorry Shiner. That was a deliberate little poke. I’ll quit. It seems as though the 4.2 pump must be much less likely to fail as compared to the first years of manufacturing. If the failure rate was of concern to Cummins or Ford you’d think they’d change fuel system suppliers, or at least threaten to change, in order to force Bosch to come up with a better design.
I would say that is not the case with Ford who have been using the pump with mediocre results since 2011. They are well known for continuing to push cr@ppy designs on customers.....6.0L, 6.4L and now the CP4 pump for years. It drove this Ford fanboy and several others I know to the competition! :B- And the passive aggressive kindergarten "mine is better than your" jabs continue. Why even bother to say "sorry Shiner" when you know you aren't.
- Ya I should have known better than to even think that Ram upping their ratings could have anything to do with them trying to be more competitive with the Powerstroke.

Huckleberry,
Just a response to your statement a while back and your comment that cummins let's the other manufactures work out the kinks before they jump on board type of excuse. And no problem as I can provide responses to those types of statements as well as cummins has some kinks to work out for themselves right now.

Yes, but you cherry picked my statement to suit your predetermined narrative to throw rocks to make this into a brand thing when it isn't. That is the difference between you and I. For you it is always about your favorite brand versus brand another and you think that others think the same way when they don't. Just like the grouping thing from earlier in this thread where you were thinking that I meant something that wasn't even the case.
I don't purposely go out of my way in threads about a Powerstroke just to pi$$ on someone else's engine choice and say mine is better than yours like a 6 year old would. And yes, I think Cummins owners are being childish when they do it in PSD/Dmax threads as well.
BTW, I just want to state here that I grouped PSD and Dmax together because I own a Cummins. I would have grouped the CTD and PSD together if I owned a Duramax or Dmax and CTD together if I owned a Powerstroke. I don't want you to inject your brand warfare way of thinking into my statements again.
The last I checked this thread has nothing to do with a Power Stroke and a Duramax. My interest originally was the news of more power from cummins and for me it's no surprise, but couldn't put the blind folds on the other bs and yes I will continue to call people out like I've done so many times on this forum.
Exactly, this thread had nothing to do with Powerstroke yet some PSD owners found a way to bring it in so I called it out just like you would..... looking at 4x4Ford.ShinerBock wrote:
